Myasthenia gris typically does not affect your life expectancy. But some severe complications, such as respiratory failure, can be life threatening, particularly in the early years of the disease.
Myasthenia gris (MG) is a rare autoimmune and neuromuscular disease that affects the connections between your nerves and muscles. It can cause significant fatigue and weakness of certain voluntary muscle movements throughout your body, often disrupting everyday activities.
Experts estimate that 150–200 per 1 million people worldwide he MG. There may be 30,000–60,000 people living with MG in the United States. However, because the disease is underdiagnosed, the actual number is likely higher.
MG is a progressive disease, so it’s important to recognize how the symptoms may change and progress over your lifetime.
